Which material can be used as a vent connector?

Galvanized steel is commonly used as a vent connector due to its durability and resistance to corrosion. In mechanical systems, vent connectors are instrumental in allowing gases, such as those from combustion processes, to safely exit the building. Galvanized steel's properties ensure that it can withstand high temperatures and the corrosive effects of the gases it conveys, making it suitable for venting applications.

Other materials, while they may have specific applications in different contexts, do not share the same level of suitability. For instance, plastic can be susceptible to melting or degrading at high temperatures, which makes it less suitable for vent connectors in many situations. Fiberglass, while used in some specialized applications, does not provide the robustness needed for general venting purposes. Wood is not typically suitable at all due to its combustibility and potential for structural failure when exposed to heat and gases. Therefore, galvanized steel stands out as the clear choice for vent connectors in compliance with the International Mechanical Code.
